What is it?
- This is my own method of nasal shape analysis that I developed personally, it's not based on any known system of analysis used in scientific papers, only because any system or approach I've found in cephalometric analysis in relation to nasal morphology was either not relevant enough to attractiveness or didn't have a single, useful universal formula, which includes all the relevant parameters to determine how close a particular nose shape to "perfection".
What this method does:
- This method allows you to determine how close to perfection a particular nose shape (side profile) on a spectrum from downturned → perfect → upturned. You may ask: "Why can't I just look at the nose and determine it intuitively?", and you indeed can. But as there's a lot of counteracting parameters, so it's not that easy to account for each of them intuitively. This method includes all the relationships of the relevant nose shape parameters to determine accurate results despite the complexity of interactions of all parameters between each other. Basically, this way you can get a single accurate answer (value), which includes all the relevant parameters.
Why only side profile nose shape?
- This method DOES account for some crucial nose shape parameters when viewing from front, even tho I don't analyze the front pic, you'll get how by the end of this post
- Other nose parameters from the front aren't complicated, no reason to make any analysis system cos it's just:
1. 0.67x of the mouth width (if mouth width is fine, lol)
2. 1/5 of bizygomatic width (if it's fine too)
3. At least a bit refined nose tip.
How this method works:
- Nose shape can be either too downturned and droopy looking, perfect, or too upturned (too short).
- Both downturned and upturned are not ideal.
- To avoid any measurement errors, the picture is always aligned in Frankfurt plane before you start the analysis.
-There are 4 parameters to determine where a person's nose shape falls under on the mentioned spectrum:
1. Dorsal angle (counting deviation from 180° or straight line)
2. Supratip break angle (counting deviation from 180° = straight line)
3. Nostrils axis angle (inclination to horizon)
This one is a bit tricky: you need to connect the posterior endpoint of nostrils and the anterior upper endpoint of nostrils.
4. Septum inclination angle (inclination to horizon)
The perfect values for each of 4 angles are:
1. Dorsal angle - 0° (straight nose).
2. Supratip angle - 0° or slightly above.
3. Nostrils axis angle - 7°.
4. Septum inclination angle - 10° to 15°.
The final formula (I'll use Delon values as an example):
1. X = Sum of person's values for dorsal and supratip angles.
X = 0 (dorsal angle) + 15 (supratip angle) = +15
2. Y1 = Person's value minus perfect value for nostrils axis angle.
Y1 = 7 (nostrils axis angle) - 7 (perfect value) = 0
3. Y2 = Person's value minus perfect value for septum inclination angle.
Y2 = 8 - 13 = -5
4. Y = (Y1 + Y2) / 2
Y = (0 + (-5)) / 2 = -2.5
5. X + Y = Person's total nose shape value.
X + Y = +12.5
Interpretation of the results. Person total nose shape value:
Downturned shape:
-30° up to -40°: maximum downturned nose shape = lower end is turbo unappealing.
-20° to -30°: significantly downturned nose shape = lower end is significantly unappealing.
-10° to -20°: not perfect, but fine = not much of a looksmin at this point (but lower = worse).
Example:
Gandy is around -36°
Opry is around -10°
Perfect shape:
0° to -10°: around perfect = practically perfect (but lower = worse).
0° to +10°: perfect.
+10° to +15°: around perfect = practically perfect (but lower = better).
Example:
Delon is +12.5°
Upturned shape:
+15° to +25°: not perfect, but fine = not much of a looksmin at this point (but lower = better).
+25° to +35°: significantly upturned nose shape = higher end is significantly unappealing.
+35° up to +45°: maximum upturned nose shape = higher end is turbo unappealing.
Example:
Basso is around +35° here
Accuracy:
This method is pretty accurate, cos even if you mess any angle by a couple of degrees, it's not that sensitive and the result values would still reflect the actual nose shape.
Limitations:
This method does not include everything. So there's still a really low chance of having a bad looking nose despite having the perfect values according to my method. It's not cos I don't know how to include everything, I know exactly how to make it work every single time. I keep it this way just to reduce the unnecessary complexity of the analysis, cos the chances of inaccurate results are so low, it's not worth it to include all the not so generally useful but time-consuming angles just to avoid the chance of 1 inaccurate result out of like 1000.
